Description

[Detailed description of the invention] (1) Purpose of the invention The purpose of the invention is to provide an airtight telescopic door that can be easily assembled and manufactured at low cost.

(2) Conventional technology and problems Curtains made of cloth, vinyl sheets, etc. have traditionally been used for simple partition doors in houses, large halls, factories, etc., but since they do not use frame materials, It could not be used to satisfy its function as a partition because it could be turned over or fanned out. In addition, although accordion doors, which are retractable doors, are currently widely used, their structures are very complex, so most of them are manufactured in factories and sold as standardized products.
The reality is that the price is high and it is difficult to make it custom-made.

(3) Means for solving the problem and examples thereof The present invention was devised in view of the above-mentioned drawbacks, and will be explained below based on examples. Fig. 1 shows a vertical lattice bar 1 of a retractable door according to the present invention. The central part 11 of the vertical lattice bar is formed hollow, and both ends are formed into C-shaped groove parts 12, 12' to be arranged oppositely.
Into the groove 12, the soft plastic sheet 3 covering the entire surface of the extendable door is pushed and fixed together with the ridge 4, and in the other groove 12', pantograph type link devices are arranged at least in two stages, upper and lower. One bent part 2a of the link device is pivotally supported on the vertical lattice rod 1, and the other bent part 2b is supported by the shaft 23, which is inserted into the slider 22 fitted in the groove 12'. It is inserted and pivoted so that it can slide upwards and downwards. Figure 2 is a front view based on one embodiment of the present invention, in which 5 is a hanger rail, and hanger roller 6 is conveniently arranged and fixed to the upper end of the vertical lattice bar.
It is a trajectory that suspends. A guide rail 7 is a guide groove for a group of vertical lattice bars. The opening/closing mechanism of the telescopic door is the second one.
The present invention is not limited to the method shown in FIGS. 3 and 3, and a lower door roller driving method as shown in FIG. 4 or a lower slider driving method as shown in FIG. 5 may be used. Figure 3 is a longitudinal sectional view of Figure 2, showing the telescopic door A and the hanger rail 5.
Since there is a gap between the hanger rail 5 and the hanger rail 5, a C-shaped groove 51 is provided in the side piece of the hanger rail 5, and the banner 52 is pressed down and fixed with a pusher edge 53.

(4) Actions and effects of the embodiment The extendable door with the above configuration will be explained with reference to FIG. 2. The plastic sheet 3 is connected to the link devices 2, 2...
Vertical lattice bars 1 regulated in parallel motion by...
1, . . . are fitted and fixed into the C-shaped groove portions 12 with the ridges 4. Now, when the door end A1 of the retractable door A is opened toward the hanging base A2, the plastic sheet 3 is partitioned at equal intervals and folded freely, so the operation is smooth, orderly, and very aesthetically pleasing.
In addition, the vertical lattice bars are hollow in the central part 11, which significantly improves the cross-sectional performance and provides rigidity, so even if wind pressure is applied to the telescopic door A, it can be blocked and can withstand even when people are moving. be. Therefore, installing a retractable sheet-lined door with a transparent sheet pasted on it at the entrance of a factory will provide sufficient light and be convenient as a simple door that is easy to open and close. When installed in conference rooms, homes, etc., it is effective as a partition door with a fashionable feel, and when installed on a residential window, a sheet-lined extendable door covered with an opaque sheet can be used as a blind door to protect privacy, provide sunshade, It has a wide range of uses, including crime prevention and prevention of damage to window glass caused by flying objects during typhoons, and has great practicality because it has a simple structure and can be made at low cost.
